LOCK.

Application led February 18, 1921. Serial No. 445,945.

Our present invention relates primarily to improvements in locks for automobile steering wheels and the like and includes among its objects the following: to provide protective means whereby to `prevent persons seeking to steal an automobile from sawing open the lock and thereby destroying its value as a protective means; to provide means for preventing the locking bolt from becoming easily set in locking position, accidentally; to improve upon the means for holding the lock cylinder in place within the lock body; and such further objects, advantages and capabilities as will later more fully appear.

Our invention further resides in the combination, construction and arrangement of parts illustrated in the accompanying drawing, andwhile we have shown therein a preferred embodiment, we desire the same to be understood as illustrative only and not as i limiting our invention except as defined in the claims.

In the 4drawing annexed hereto and forming a part hereof Fig. 1 is a sectional plan showing the interior construction of our new lock and its relation to the steering post; Fig. 2 is a longitudinal section substantially along. the broken plane indicated by the line 2-2 Fig. l; and Fig. 3 is a section substantially along the broken plane indicated by the line 3--3vl3`ign 1. l

Referring more in detail to the annexed drawing, numeral 1 designates the cap of the steeringcolumn, while numeral 2 designates the lock casing formed integral with the cap 1 and-containing the lock parts. The steering ost 3 has keyed or otherwise appropriate y secured thereto a ring 4, provided around its periphery with a plurality of apertures 5 for the reception of the locking bolt 6 which slides in an aperture in the casing 2 as is evident. A spring 7 in this aperture rests against the outward end of bolt 6 to cause the same to be forced inwardly to locking position.

A notch 8 is cut in one side of the locking bolt 6 so as to leave a iange 9 at the outward end thereof, adapted to be engaged by vthe pro'ection 10 on the inner end of the lock cylinder. It will be obvious that when this cylinder is turned the projection pin or roller bearing 10, lengaging iiange 9, willforce lockingpluiger 6 backwardly out of engagement with eaperture 5 in collar 4,

on spring 7, so

having a bevelled face 12 designe to be engaged .by a corres onding face 18 on latch 14', which is forced) upwardly into the aperture 11 under the influence of a spring, as will be described later.

In the side of bolt 6, opposite that in which is located the aperture 8, is another aperture through which passes a bolt 15 provided with a head 16 adapted to be engaged by a spring 17 which surroundsy the bolt 15 and forces the same upwardly when the bolt is free to move in that direction. The lower end of this bolt is shown as being screwed into an aperture in latch 14, and it will therefore be seen that when bolt or plunger 6 is withdrawn from locking position spring 17 will force bolt 15 outwardly, carrying latch Minto aperture 11. When in this p0- sition, faces 12 and 13 will be in engagement and, because of their inclination, will prevent latch or block 1 4 from being easily disengaged,vaccidentally, from locking bolt 6. It will be seen from this that sudden jolts of the car due to obstacles or unevenness in the roadway cannot cause the accidental release of the plunger 6 so as to cause accil 'dental locking of the steering post. Furthermore, with this arrangement, there is much less likelihood of accidental touching of the head 16 of bolt 15 causing the release of plunger 6, 'whereby to cause locking of the-steering post.

A screw 18 having a reduced entering end is inserted into a screw threaded aperture in the cap to engage the lock cylinder and hold the same in place in the casing 2. Since this screw 18 is inserted by way of the aperture in the cap 1 and casing 2, which is subsequently illed by collar 4, there is no way for this screw to be removed from the exterior so that thel interior of` the lock can be vgotten at.

At convenient points in thecasing 2 are formed apertures for the reception of very hard tough members 19, such as pieces of piano wire. These are here shown as exltending substantially parallel to the lock cylindery so as to prevent a erson from sawlngk'crosswise Athereof an destroying the It is of course obvious that similar Wires can be inserted in the casing 2, substantially at right angles to those shown, so as to prevent a person from sawing off the outer end of casing 2 and removing the spring 7, thereby rendering it possible to withdraw locking bolt 6 from its position in engagement with one of the sockets 5.' It is well understood that the presence of the hard wires 19 in the softer metal of the lock will cause the destruction of any saw blade with which one may attempt to destroy the lock. Though these wires may be inserted in only one direction, it is considered preferable that they be inserted in two directions at substantially right angles, so as to prevent sawing the locks in either direction.

It is of course understood that the specific description of structure set forth above may be departed from without departing from the spirit of our invention as set forth in this specification and the appended claims.

Having now described our invention, we claim:

1. In a structure of the character described, a casing, a spring pressed bolt slidable therein, said bolt having a notch in one face thereof adapted to be engaged by a latch member, one face of said notch being inclined inwardly and backwardly to serve as bolt latch ho ding means, and a spring pressed bolt latch adapted to be seated in said notch by spring pressure and having an inclined face adapted toco-operate with the inclined face of the notch in the bolt to assist in preventing accidental release of the bolt from withdrawn position.

2. In a lock, a casm a spring pressed bolt longitudinally slida le therein, said bolt having a notch in one face thereof adapted to be engaged by a latch member, one face of said notch. being inclined inwardly and backwardly toward the spring, and a spring pressed bolt latch `adapted to be seated in said notch by spring pressure and having an inclined face adapted to co-'operate with the inclined face of the notch in the bolt to assist in preventing accidental release of the boltv from withdrawn position, and a second bolt extending through said casing transversely to the direction of the first named bolt and carrying the said latch, whereby the latch may be released from the notch by longitudinal movement of the second named bolt.

3. In a steering wheel lock, a casing, a spring pressed bolt slidable therein, ke controlled' means for withdrawing sai bolt against the tension of its spring, said bolt having a notch in one face thereof adapted to be engaged by a latch member, one face of said notch being inclined inwardly and backwardly to serve as a latch holdin means, a second bolt extending through sai casing transversely to the direction of the first named bolt, a spring encircling said second named bolt to bias the same outwardly a bolt latch carried by the inner portion of said second named bolt and havin a face inclined in the same direction as t e inclined face of the notch and adapted to co-o erate therewith to assist in preventing acci ental release of the bolt from withdrawn position.

4. Ina lock, a casing having an aperture for the reception of alo'cking bolt and an opening for the reception of a member to be locked by said bolt, said casing being provided with a chamber-extending inwardly from an outer face thereof Ato the bolt receiving aperture and adapted to receive a lock cylinder therein, an aperture extending from said opening through the casing into the lock cylinder receivin chamber, a lock cylinder mounted in sai chamber, and a holding member extending through said sec'- ond named aperture into the cylinder receiving chamber and into engagement with the cylinder to hold the same in place within the casing.

In witness whereof, we hereunto subscribe our names to this specification.
